FIN1031
3.3V LVDS 4-Bit High Speed Differential Driver
FIN1031 3.3V LVDS 4-Bit High Speed Differential Driver
General Description
This quad driver is designed for high speed inte rconnects
utilizing Low Voltage Differential Signaling (LVDS) technology. The driver translates LVTTL signal levels to LVDS levels with a typical differen tial output swin g of 350mV w hich
provides low EMI at ultra low power dissipation even at
high frequencies. Th is device is ideal for hi gh spe ed tran sfer of clock and data.
The FIN1031 can be paired with its companion receiver,
the FIN1032, or any other Fairchild LVDS receiver.
Features
■ Greater than 400Mbs data rate
■ 3.3V power supply operation
■ 0.4ns maximum differential pulse skew
■ 2.0ns maximum propagation delay
■ Low power dissipation
■ Power OFF protection
■ Meets or exceeds the TIA/EIA-644 LVDS standard
■ Pin compatible with equivalent RS-422 and LVPECL
devices
■ 16-Lead SOIC and TSSOP packages save space
